mem_cgroup_id_get() was introduced in the commit 73f576c04b94 ("mm:memcontrol: fix cgroup creation failure after many small jobs").
Later, it no longer has any user since the commits,
1f47b61fb407 ("mm: memcontrol: fix swap counter leak on swapout from offline cgroup") 58fa2a5512d9 ("mm: memcontrol: add sanity checks for memcg->id.ref on get/put")
so safe to remove it.
